The Beluga is noteworthy for its cameo appearance in X: Beyond the Frontier during the game's tutorial. This makes it the oldest canonical Terran missile in terms of age.
This is the popular Terran missile called the Beluga. It is the standard earth fleet missile used onboard fighter craft.
The Beluga is a Terran missile, but curiously is only compatible with Commonwealth ships. It is capable of demolishing all but the heaviest of fighters in one hit, and its high compatibility mean that one can pop out of a launch tube in pretty much any fight. They are rare, however, and cannot be bought or manufactured anywhere.
